SIXTH CENTURY. Ascetic and writer. Initally influenced by Barsanuphius, he founded a monastery near Gaza in Palestine about 540 and became its archimandrite. For the members of the community he wrote Didaskaliai Psychopheleis, instructions on the life of discipline and asceticism. He made use of earlier collections of rules and added to them his own insights. The later standard edition of the Didaskaliai contains further additions to Dorotheus's original rules. He placed great emphasis on humility, maintaining its supremacy over love and its basic relationship to all other virtues.
